Application filed May 16, 1912. Serial No. 697,593.

To all whom it may concern:

Be 1t known that I, CLARENCE IV. LAKIN,

.a citizen of the United States, residing at Haverhill, in the county of Essex and State of Massachusetts, have inventcdan Improve,- melqt in Heels for Shoes, of whichthe follow is. a specification.

In aching high heels with certain types of heeh g machines, it is customary to attach th heels-in two sections, the base portion being first attached to the heel seat of the shoe, and then a top portion being atcached, to the base portion. These two heel sections, previous to attachment, are highly compressed in a heel compressing machine, and the surfaces of said sections, which are brought together when the second section is attached, are usually very bar and smooth. The-result is, that, as there is a strong tendency to cause the upper section to slip rear wardly, as the nails are driven to attach it to the lower sect-ion, the upper section frequently slips out of place on the lower section, so that it will either not be attached inthe desired position, or' what is more likely, the attaching nails will be crippled. In either case the heel must be detached and the operation repeated.

The object of my invention is to provide 'heel sections which are so constructed that they will interlock and rearward slipping of the top section upon the base section will be prevented. I accomplish this object by providing the contacting surfaces of the two.

sections with transversely extending, interlocking corrugations in the manner hereafter described and illustrated in the ing drawing, in which,

Figure 1 is a side elevation of a heel made according to my invention. Figs. 2 and 3 are, respectively, a plan view and, aside elevation of the base section. Figs. 4 and 5 are, respectively, a bottom plan view and a side elevation of-the top section, and Figs. 6 and 7 are detailed views showing dilterent forms of interlocking ribs which I may employ. I

According to my invention, the base section a, which is adapted to be attached diaccom'panyrectly to the heel seat of the shoe, is corrugated to provide a series of transversely eX- tending ribs (4, and the top section b is also corrugated on its base surface to provide a series of transversely extending ribs b, which correspond in size and spacing to the ribs a" of. the base section.

In practice when the base section a has been attached, the top section?) is pressed thereon causing the ribs 7) to enter the spaces between the ribs a, so that they interlock, as illustrated in Fig. 6, with the result that the horizontal force, which would tend to cause the upper section to slip on the lower section, will be resisted to a sufficient extent to prevent such an occurrence under ordinary conditions.

The particular form of ribs which I may employ is not essential as they may be made rounding, as shown in Fig. 6, or sharp, as shown at a in Fig. 7.

As the above described ribs on the contacting surfaces are formed during the molding operation, the expense of forming them is practically nothing.

The result which is accomplished would not be accomplished to any appreciable or practical extent, by merely corrugating one of the sections. as the ribs on one section only, would not have any penetrating effect on the highly compressed, smooth surface of the other section, and it is only by the interlocking of the ribs that the desired results are secured.

I claim A heel composed of a base section and a top section having engaging faces, said tacos having transversely extending inter-engaging ribs for holding said sections "from relative slipping movement longitudinally of the heel, substantially as described.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

CLARENCE IV. LAKIN.
